Introduction
------------

This program (Advanced ARJ Password Recovery, or simply AAPR)
can be used to recover the lost passwords for a ARJ and WinArj
archives. At the moment, there is no known method to extract
the password from the compressed file, so the only available
methods are "brute force", dictionary-based and known-plaintext
attacks.

Well, there are a lot of programs like this around, but
all of them have their own "pros" and "cons". Here is a brief
list of AAPR's advantages:

- The program has a convenient user interface
- The program is very fast: about two million passwords per
  second (on Pentium II)
- Self-extracting archives are supported
- The program is customizable: you can set the password length
  (or length range), the character set to be used to generate
  the passwords, and a couple of other options
- You can select the custom character set for brute-force attack
  (non-English characters are supported)
- Dictionary-based attack is available
- The "brute-force with mask" attack is available
- The maximum password length is not limited (in registered
  version)
- Very fast known-plaintext attack is available
- No special virtual memory requirements
- You can interrupt the program at any time, and start from the
  same point later
- The program can work in the background, using the CPU only 
  when it is in idle state

The next versions will have much more useful features, of
course.


Requirements
------------

- Windows 95 (any version), Windows 98, Windows NT 4.0 or
  Windows 2000 running on Pentium CPU
- 4 megabytes of RAM
- about 1 megabyte of hard disk space


Known bugs and limitations
--------------------------

- The program might not work with archives created with ARJ
  newer than version 2.60.
- When files in archive are "stored" (ARJ method 0) or packed
  with method 4, the performance might be lower than expected,
  because unpacking the whole file is required.
